A fiber-optic quasi-distributed strain sensors ring network has been designed based on a Mach–Zehnder optical paths interrogator. The optical paths matching for each sensor are discussed, and the optical power budgetary analysis is performed. The relation between the number of sensors and the intensity of the signals of the ring network is given for evaluation of the multiplexing capacity. Experimentally, a seven-sensor array ring network was realized under the condition of light source power 35 W at 1310 nm, and the distribution strain test was also demonstrated.
